Formula: B
Form: Rod
Material: Boron
CAS Number: 7440-42-8
Commodity: Metals
Purity:
99.6%
Diameter:
5mm
Our Boron Rods are made from high-purity boron and are available in a range of diameters and lengths. With their extreme hardness, high elastic modulus and excellent corrosion resistance, these rods are used in specialized scientific and industrial applications. For example, they may be incorporated into control rods for nuclear reactors. Their ultra-high purity also makes them ideal for semiconductor manufacturing and other applications requiring impurity-free materials. With 13 size variations to choose from, our Boron Rods provide flexibility to meet diverse application requirements.
